You have complete access to the data that the user has entered in the form. While the form is being processed, this data is held in the edit buffers for the fields; the underlying data variables are not normally updated until the user exits the form. (There are two exceptions to this, for scrollable regions and for fields with the FORCECONVERT option turned ON. These exceptions are discussed earlier in this chapter.)
Vermont Views provides functions to allow you to get the information that the user has typed, and to update fields on the form, while the form is still being processed. These functions are most useful when you are writing your user functions. These functions should not be called when the form is not on the screen. They can, however, be called if the form is on the screen but is currently covered by another form or window.
